Subpanel Main Breaker Requirements: Nec Guidelines

Whether a subpanel requires a main breaker depends on its configuration and the National Electrical Code’s (NEC) regulations. In general, a subpanel derived from a main breaker panel does not need a main breaker, while one derived from a fused disconnect switch panel usually requires one. The NEC specifies that a subpanel without a main breaker must be protected by a circuit breaker or fuse in the main panel or switchboard that it is derived from.
